## Discrepancy

DURING LANDING FLARE, AILERONS BECAME EXTREMELY STIFF ALMOST AS THOUGH AUTO PILOT WAS STILL ENGAGED.  PRESSING CAPTS A/P TRIM DISC HAD NO EFFECT.  STIFFNESS CAUSED ROLL OSCILLATION. STIFFNESS BROKE LOOSE BY MOVING AILERONS AFTER LANDING AND FELT LIKE A/P DISCONNECTED.  REPLACED AUTO PILOT AILERON SERVO.  OPS CHECKS GOOD.
